Most common hardware problems

In this post I will summarize most common laptop hardware related problems and give some suggestions how to troubleshoot or repair them.

Problem 1.
Computer doesn’t turn on at all.

When you plug the AC adapter into the laptop, there are no lights turning on at all. When you push on the power button, nothing happens. The laptop appears to be completely dead, makes no sounds, no indications of life.

Possible problem:
– The AC adapter failed and the battery has no charge left. In this case test the AC adapter with a voltmeter. If it’s dead, replace it with a new one.
– DC jack failed and the motherboard doesn’t receive any power from the adapter. In this case the DC jack has to be replaced.
– Motherboard failed. The motherboard has to be replaced, if it’s not too expensive. Otherwise get ready to buy a new computer.

The laptop turns on, power LED lights up, cooling fan works but nothing appears on the screen. The screen is completely black and blank. There is no image on the screen at all.

Possible problem:
– This can be memory failure. It’s possible one of the memory modules failed. In this case you can try reseating memory modules to make sure they are making good contact with the slot. You can try removing memory modules one by one and test the laptop with only one module installed. You can try replacing memory modules.
– If reseating/replacing memory doesn’t help, try removing the hard drive, DVD drive, modem, wireless card, keyboard, etc… In other words, disassemble the laptop to bare minimum and test again. If the laptop still doesn’t turn on, most likely you have failed motherboard or processor.

The laptop turn on without showing any image on the screen. After a few seconds it turns off by itself. Then it turns on and off again.

Possible problem:
Most likely this is motherboard failure. You can try reseating/replacing memory as I described in the Problem 2. If it doesn’t help, probably the motherboard failed.

Problem 4.
Laptop makes noise while running.

The laptop turns on and everything works fine, except it makes some constant weird grinding or rattling noise.

Possible problem:
In most cases this noise is coming from the cooling fan or hard drive. Take a closer look at the cooling fan.

If the fan doesn’t spin but the the laptop makes noise, probably it’s coming from the hard drive. Back up all personal data as soon as possible and replace the hard drive.

Also, you can remove the hard drive and stat the laptop. If the laptop still makes noise, most likely it’s bad fan.

Problem 5.
Laptop shuts down or freezes.

The laptop runs properly but after a while it freezes or shuts down without any warning. When it happens, the bottom feels hot. Also, the cooling fan runs louder than usual.

Possible problem:
Most likely this is heat related issue. It happens because the fan heat sink is clogged with dust and the processor not cooling down properly. Cleaning the fan and heat sink from dust should fix it.

The laptop turns on properly but has a distorted or garbled image on the screen.

Possible problem:
– The graphics card failed. First of all, test your laptop with an external monitor or TV. If you see the same garbled image on the external screen, most likely the graphics card failed.
– If the problem appears only on the laptop screen, this can be related to one of the following: poor connection between the video cable and motherboard or screen. Also can be failed video cable or screen.

You turn on the laptop but there is no video on the screen. Instead, it starts making repetitive beeping sound. In some cases you can “fix” the problem temporarily if you press on the keyboard keys.

Problem solution:
Most likely you have stuck keys. In this case you’ll have to replace the keyboard.

Problem 12.
Liquid spill.

You spilled something on the laptop and it’s stopped working.

Problem solution:
Liquid spills are very dangerous and unpredictable. If it happened, turn off the laptop ASAP, remove the battery and do not use it until all internal parts are inspected for liquid damage.
It’s sill possible to make it work again.

My problem is similar to Problem 5 but here’s the difference: the laptop turns down ONLY when I’m playing games. When I use Firefox it stays on all day long. Is it also overheating?

Definitely this sounds like heat related issue. When you run games, the CPU is loaded all the time and runs hot all the time. Probably the heatsink is clogged partially and CPU overheats when you running games. Try cleaning the heatsink. It should help.

I have a HP Pavilion g6 laptop. 2,w,s,x keys stopped working. I want to replace the keyboard but I don’t know how.

This definitely sounds like a problem with the keyboard.
You can use find keyboard replacement instructions in the HP service manual.
1. Remove the battery.
2. Remove one screw shown in the step 7.
3. Remove the keyboard as it shown in steps 8-13.
Good luck!

In response to Alex. Yes, in my experience I can’t stress enough how many heat issues (as well as other issues) can be solved by blowing out the dust and dirt and cleaning the cpu heatsink fans and videocard heatsink and fan if there is one. There are also laptop cooling pads that you can use during the game if you really had to! I also would do malware and virus checks and scans to make sure there isn’t something unnecessarily running and using more CPU in the background than is necessary. Hope you have resolved your issues.

I have dell 1440 laptop(CDrom is not working),due to some mistake, the windows crashed and everytime i power on it, this message appears “Boot Manager is missing, click ctrl+alt+del to exit” ,Is this a hardware problem? how could i install windows 7 back easily?

Wahab Imran

please I want you to email me. what are the component that someone can heat on a laptop board and also my laptop was hanging on booting to window I now check the memory, harddisk, processor is till not working I now give it another engineer he now said that his going to work on the board and later the laptop become operational. pls what are the likely things he may do on that board. I beg u in the name of God pls email me back.

It’s hard to tell if this is hardware or software related issue. Could be just corrupted Windows OS. Could be hard drive failure.
First, I would test the hard drive. Run internal Dell diagnostic utility and see if the hard drive passes test.
If the hard drive is OK, you’ll have to find a CD-Rom. You cant try fixing the existing Windows OS installation by booting from Windows 7 CD and running OS repair.

Hi does an ac adapter have to give a steady voltage for it to work correctly as I have an adapter that is reading an initial 19v but then drops back to 0 again without disconnecting anything.

However I’m guessing the adapter itself is ok as the machine actually turns on it you hold the adapter plug in tight and sometimes also in a certain direction but its so sensitive it only stays on for a short time. Do you think its likely to be a mobo short or a problem with the DC jack? The DC jack has no loose connections on the board as far as I can see.

Does an ac adapter have to give a steady voltage for it to work correctly as I have an adapter that is reading an initial 19v but then drops back to 0 again without disconnecting anything.

This is not normal. The AC adapter has to provide a steady voltage.

I’m guessing the adapter itself is ok as the machine actually turns on it you hold the adapter plug in tight and sometimes also in a certain direction but its so sensitive it only stays on for a short time. Do you think its likely to be a mobo short or a problem with the DC jack?

This could be one of the following:
1. The AC adapter cable has a short inside. When you move the adapter plug or adapter cable you short cables and it stops providing power to the laptop.
2. The DC jack separated from the motherboard and has to be resoldered or replaced.

Here’s what I would do:
1. Test voltage on the AC adapter tip. While testing the voltage, wiggle the power cable. If power cuts off, this is defective AC adapter. Replace it.
2. If the AC adapter provides steady voltage even when you wiggle the cable, probably the AC adapter is bad and you have a problem with the DC jack. Try resoldering the DC jack.

The DC jack has no loose connections on the board as far as I can see.

It’s possible the solder joint has a micro crack which you cannot see. It’s a common DC jack failure.

No corrosion or any liquid inside the laptop!…

Thanks in advance!

i have an hp laptop, problem is that all ports on the machine are disabled meaning they are not functional and you cannot get anything into the machine or out of the machine.when you check the settings it says all ports are disabled and when you enable them and try to use a stick or flash it would have disabled already by itself.what could be the problem and how do you fix it.

Sounds like the motherboard related failure. Sorry cannot help here. I don’t fix motherboards on the component level.

This is a very weird problem. I’ve never seen something like that.
Does it say that all ports are disabled in the BIOS setup menu? Is it an error message in Windows?

Help! Okay the LCD screen on my laptop was broken, cracked in the corner after someone closed it with a pen on the keyboard..

I decided to replace the screen myself.. I took it apart got the serial number and ordered the replacement screen. Installed the new screen and nothing shows up except colored portions and lines. Figured it was a defective screen and sent it back for a replacement.

Got the replacement screen and the same thing happens!

Am I doing something wrong? Or is it that I just keep getting defective screens?

Thanks..

Maybe your new screens are not compatible.
What happens if you install the cracked screen back into the laptop? Can you get image on the cracked screen?
If your old screen shows image but new screens have only vertical lines, this is some kind of compatibility issue.
Make sure your new screen has same resolution as the original one.

not sure if you installed the hard drive in a correct manner. Just to be sure about it, you can access the bios (normally F2 or f10 key while restarting) by hitting the bios key during Power on Self Test. If the hard drive is not showing in the list of drives, you probably have either connected the wires wrong or may be your HD is dead. Besides, you can also look for the green light near the keyboard that has the pic of a HD. If that is not lit or not flickering, there is something wrong either with Hd or the way it is connected.

I have a HP Pavilion dv7 laptop, I know that the battery has died in it. It was going bad for some time and now it’s dead. My issue is this. The Wifi won’t connect to my router although it see it and has a full signal. I sent it in for repair as it has a warranty on it, and they sent it back saying the dead battery was the cause.

Is this true, can a dead battery cause your wifi to do this even though you are plugged into the outlet?

Thanks, Dean. (PS OP feel free to email me if you want / can)

My problems is similar to what is shown above. The back light of my laptop screen goes off after few seconds while booting. Even though I can see the screen and give login password. I can see the desktop icons and work but have to have a closer look at screen or use other light like flash or torch. In two cases light comes back also. First, when I close and open the lid again and secondly, when the mouse pad is touched after the display of off as per time set (thus the lids is not moved in this case). In every case the light remains for not more that 4-5 seconds.

Please suggest what can be the problem and if possible the cost involved.

Thanks for the time and considering to reply.

My Dell laptop just died on me an hour ago and it’s totally dead,no lights come on either,its just dead!
I check the ac adapter and that is working fine on my other dell but this one is dead. I have most of my design work on my pc as im a graphic designer and i created my portfolio on this pc 2 years ago and now what do i do?
Please help. Any other ideas.

cj2600

I check the ac adapter and that is working fine on my other dell but this one is dead.

If the AC adapter works with another laptop, probably it’s not the adapter failure.
Most likely it’s either bad DC jack or failed motherboard.

In order to backup data from the laptop you can do the following. Remove the hard drive from the laptop and install it into an external USB enclosure. Connect the enclosure to any other working PC and get your files.

By the way, if you have a SATA hard drive you can connect it directly to the PC. Most laptop SATA hard drives has same type of connector ad desktop hard drives.

I would run the hard drive and memory test first. Enter the BIOS setup menu. It’s likely that you HP has utilities for testing the hard drive and memory embedded into the BIOS.

Maybe NumLock enabled?

I have a Toshiba Satellite M305-S4910 with 3.9 amperage output. Recenetly I had to purchase a new AC adapter 120W with 6.32 amperage. I wanna know if this big difference in AC amperage will hurt my laptop or not.
Thanks for any advice.

My Packard Bell Easynot L4 fell and the DC Jack broke.
I replaced this, but now when powered up the power light comes on aswell as the fan. The screen is black, but I dont think it is going any further as the hard drive light doesnt come on/flash.
I just read above to try an external monitor. Other than that is it curtains for the laptop ?

Did you check the memory modules? Maybe one of the modules not seated correctly. Try reseating memory modules. Also, test the laptop with only one module installed.
Did you try turning it on with the hard drive removed?

If your new AC adapter has THE SAME voltage but higher amperage, it’s OK to use. It will not damage the laptop.

Yes I had tested my laptop with another AC adaptor. But it did not solve my problem.

This could be one of the following:
1. DC jack failed. You can try replacing it with a new one.
2. If replacing the DC jack doesn’t help, most likely this is motherboard failure. Probably in this case the laptop not worth fixing (depends on the model).

I had problem 5 happen at first with my toshiba laptop where it randomly froze.I tried to restart it, but now I’m encountering problem 2. Some times it turns back on, but it will just crash again. What do I do?

Windows has encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removable storage is properly connected and then restart your computer.

If you continue to receive this error, contact the hardware manufacturer.

Status: 0xc00000e9

It’s possible the laptop will not boot because it doesn’t see the hard drive.
Enter the BIOS setup menu and check if the hard drive is detected.
Try reconnecting the hard drive.
Connect hard drive to another working PC and check out if it spins.
This could be hard drive failure.

It’s hard to tell what is wrong. Yes, there is a chance of bad AC adapter.
I would test the laptop with another AC adapter. If the problem still there, probably this is motherboard related failure.

Most likely this is defective LCD screen. I think you’ll have to replace the screen.

I have a Sony Viao Laptop that was dropped and now it boots to a black screen that says Operating System not found. My first guess was that the hard drive was bad/corrupted and after research and running some scans I was right. MY question is how do I know that is all that is wrong? I don’t want to buy a new HDD then find out that other components were damaged. I was thinking of using a HDD from another laptop and putting it in the laptop that was dropped but I guess I want to know how to diagnose other components. What tools/software scans do you recommend? Also with the failed HDD do you think if I bought and IDE connector/adaptor I could connect this to a desktop and possibly recover the data or ever get the HDD to work again? Is there an USB IDE connector to hook up an hdd?

You can download Ubuntu OS and burn it on a DVD. After that boot your laptop from this disc and test in the Ubuntu environment. If everything works fine in Ubuntu OS, probably only the hard drive is bad.

I was thinking of using a HDD from another laptop and putting it in the laptop that was dropped.

You’ll have to reinstall OS on the new drive in order to use it. Most likely the OS from another computer will not run properly in your laptop.

Toshiba Satellite A300
When turning on Display comes and Turn off Automatically

Does the laptop still work after the display turns off?
Take a very close look on the screen. Do you see a very faint image on the screen?
If the laptop still works and you can see a very faint image on the screen this could be failed inverter board or failed LCD screen (actually failed backlight lamp inside the screen). I would try replacing the inverter board first.

Whenever I unplugged my charger laptop start working slow. when charger is in plug its working normal. Give me hints/support how to fix it.

Maybe you have some power settings enabled? On some laptops you can reduce the CPU speed when it runs off the battery. It makes the laptop slower while running from the battery but improves battery life.

If the battery works in another laptop, it must be some kind of motherboard problem. I’m not sure what else could be causing that.

It it very common problem in every laptop which installed with windows 8. Windows updates may cause for this issue. Solution is “Remove the battery, disconnect adapter, press and hold power button for 50 seconds. Now don’t insert battery, connect with adapter and turn the laptop on. 100% your problem will solve.

None of the desktop shortcuts functioned correctly, so I rebooted the machine. During reboot the machine would display the Dell logo and the progress bar. Once the progress bar would fill up it would then go to the Windows Boot Manager and ask me to choose an operating system (only one operating system is installed – Windows 7) it would then quickly start the reboot process over again. and loop like this until I hit any key (doesn’t matter which). After that it would load windows. once windows would fully load I still cannot select any of the shortcuts, or the start menu. until I hit the windows key on the keyboard to bring up the start menu. after that everything seems to start to respond better (at least on the surface). I then replaced the HDD and installed windows 7 Home Premium to that HDD. once loaded it did the exact same things. I then took out the battery on the motherboard waited a little bit and then put it back in. Once I reset the system date and time in the BIOS and save, windows would then start to act normal again, but after a few minutes it would resume with the same problems. I then got a new battery and placed it in the motherboard. still no change. I am all out of Ideas! any help would be great! The laptop also seems to work normal for about an hour if I power it down for at least a half day or longer.

@ Joshua,
To me this sounds like a problem with the audio driver. I’ve seen it happening on laptops with a wrong audio driver installed. Did you search for the correct audio driver on HP website?
It’s possible you installed the latest audio driver available though Microsoft update but need the original driver from HP website.

Try running Dell hardware diagnostics.
Turn on the laptop and press F12 when logo appears on the screen. Select diagnostics.
Maybe you’ll see what is failing in results.

my HP g62 does not display anything on the screen when the power button is pushed….however the fan works! Also the display works sometimes for not more than 10 minutes.Is there a problem with motherboard or any other issue?It is having inbuilt ati radeon graphics.

cj2600

@ aakash,
In order to figure out if this is motherboard related issue or not, you will have to test your laptop with an external monitor or TV connected to the VGA or HDMI port.
If the laptop video works fine on external monitor, most likely you have a problem with the screen.

Also, check RAM modules. This could be memory related failure too. Remove RAM modules one by one. Test the laptop with only one model at a time.

my computer loses charge very quickly and then it was the battery life just is completely depleted and everytime I turn it on it loses one percent of charge and after an hour or two after being out of charge it just won’t turn on at all. I brought a new battery and it still does the same thing. what can be the problem I’m starting to think its the motherboard

jamie

hey I have a hp g62
And just this morning I try turning it on the fan starts the light on the power button is showing but nothing loads up on the screen, when I try turn caps lock on the light doesn’t show either (is that also keyboard issues) wireless light shows as orange (off) not blue (on) and basically it just doesn’t do anything from there as though it freezes maybe straight after startup. Please help??

cj2600

@ jamie,
1. Unplug the AC adapter, remove the battery and let is seat like that for a few minutes. After that plug in the AC adapter and try turning it on again.
2. If step 1 doesn’t help, try removing RAM modules one by one and test the laptop with each RAM module individually. Could be failed RAM.

I have an LCD screen that sometimes shows a faded image (with horizontal white lines) and vertical multi-colored lines that slowly shift around. It’s very difficult to read when this happens. Once when I torqued the screen around the edge it suddenly snapped back to normal, but a week or so later it started showing the lines again. Then when I was browsing normally it snapped back to normal again. Do you know what might be causing it? I didn’t notice any problems with the computer until it overheated once. I have not yet tried to connect it to an external monitor; I’m too afraid to move it at this point.

Brenna

Every time I turn the laptop on, it would run fine for a few minutes, then on the ENTIRE screen would appear vertical blue lines, sometimes they flicker, sometimes not. Sometimes the screen just goes black, though I can tell it is still lit up. It’s gotten worse and worse every time I try to use it, or try to turn it on.
When this happens, I have no choice but to unplug it and shut it off without properly shutting it down. When I turn it back on, it says that it was not shut down properly, and gives me the choice to start up in normal mode, or the two safe modes. When I choose normal mode, it barely is functioning before it does the same thing: volume shuts off, screen goes black or blue vertical stripes.

The safe modes work, but I can’t do anything on them and the volume does not function.

I really, really don’t want to lose all the photos, download files, music, documents, and all other files I have saved on that computer.

How can I get these files off, and how can I fix the computer from doing this? What is wrong with it?

I hope someone on here can help me with this problem!

It’s not a very clear description of the problem. If I understood correctly, you have to restart the laptop a few times in order for the screen to work properly.
If that’s the case, check laptop RAM. It’s possible, one of the memory modules failing. Try removing memory modules one by one and test the laptop with each one separately.
Let me know how it goes.

Sometimes the screen just goes black, though I can tell it is still lit up. It’s gotten worse and worse every time I try to use it, or try to turn it on.

You will have to test the laptop with an external monitor. If the external video has the same problem, this is motherboard/graphics card related issue.
On the other hand, if the external video works fine, it’s either failing LCD screen or bad video cable.

I really, really don’t want to lose all the photos, download files, music, documents, and all other files I have saved on that computer. How can I get these files off?

Again, if the external video still works, you can boot the laptop and backup your files.
The other way is removing the hard drive and installing it into an external USB enclosure. After that you should be able to access your files on another computer.

For some reason I think this is graphics card related failure. To confirm that, test your laptop with an external monitor. If you see the same problem on the external video output, the graphics card is bad.

On my hp 620 laptop,the internal keyboard works at the booting stage but after booting, it stops working and makes a beep when it is clicked;it also happens likewise when i connect an external keyboard. please tell me the possible faults

...

i spilt a bit of water onto my keyboard however the battery of the laptop is located in the lid and the keyboard is only a dock for the tablet. I immediately cleaned it out and got the water out and everything works fine but i realised that my battery wont charge. It only works now when im connected to the ac adaptor because i only started to charge it when it was low on battery. The screen says that im plugged in but im not charging.

cj2600

@…,
What is your laptop model? It’s hard to understand the location of the battery from your description. If the battery stopped charging after the spill, most likely the motherboard was damaged.
I would stop using the laptop as soon as possible and take it apart for liquid spill diagnostic.

cj2600

@ chukwuemeka,
If both, the internal and external keyboards fail the same way, this could be software related issue.
Here’s what you can try.
1. Boot your laptop from a Live Linux CD. You can use Ubuntu or any other disctro you can boot from a disc. If the problem doesn’t appear in Linux, most likely it’s related to your current OS. Reinstall the OS.
2. Try disconnecting the internal keyboard from the motherboard and test the laptop just with the external USB keyboard. If it works properly with the internal keyboard disconnected, this could be the laptop keyboard failure. Try replacing it.

Hi I have an AcerAspire One and I increased the Ram from 1gb to 2gb I followed a Youtube video on how to do the install. I carefully worked around the keyboard not wanting to disconnect it to cause damage to it. When I put in the new Ram and replaced all the screws and put the keyboard back in place I turned on the unit. While it was coming up I got a black screen and and did the configuration by just hitting enter. The laptop continued to come up as normal but I noticed when I was typing in a search that included just the M key and spacebar these 2 keys would not work. I tried shutting it down to restart that didn’t work, I checked to see if keyboard cable was not kinked or loose, and disconnected keyboard and reconnected being very careful and still both do not work. I even downloaded updated drivers to no naval. So after trying for 5hours

Hi.
My laptop (HP Pavilion g7, if it help) keeps going from the screen that leads to the startup menu to black, usually staying on one screen for 3-7 seconds before going to the other. I’ve tried going to the startup menu, but then it goes back to what it waa doing and starts making a high pitched noise.
Any idea on what this is and how it can be fixed?

Hi, I have a HP laptop. I was watching a movie when in my laptop then I paused it, then when I pressed the resume the colors on the screen just went still but the movie is still running(it also had vertical and horizontal lines) I shut it down and opened it again hoping that it will go back to it’s original form but unfortunately it did not. I did’nt opened it for how many months and now even the keyboards don’t work and when i opened it, it will not go to the password.. It just display the model of the laptop. Windows 8. It’s still charching. Can you help, pls.. Thank u

cj2600

now even the keyboards don’t work and when i opened it, it will not go to the password.. It just display the model of the laptop. Windows 8.

Is the hard drive and RAM modules easily accessible?
1. Remove the hard drive and try turning it on. Will it pass the initial logo screen?
2. Try removing RAM modules one by one. One of the modules can be bad.

When I connect that wire. Those keys are working perfectly but my keyboard will stop working. When I disconnect that wire, my keyboard working perfectly but I am unable to use those keys.

I assume all those keys (Bluetooth, Wi-Fi, volume) located on a separate media control board. The first step in troubleshooting process would be replacing this board.
If you have the same problem after replacing the media control board, most likely this is motherboard related issue.

It’s possible the laptop shuts down because of overheating. Try cleaning the cooling fan first. Buy a can of compressed air or find an air compressor. Blow air into the fan grill on the bottom and side of the laptop. This will remove most of the dust from the cooling module and might fix your problem.

randybohanan

cj2600

the screen reads operating system not found no matter what button on key board is pushed

It’s either corrupted OS or hard drive failure.
First, I would run hard drive diagnostics. You can download Ultimate Boot CD (free) and burn it on a CD. After that boot from the CD and run hard drive diagnostics. If it fails test you’ll have to replace the hard drive and reinstall OS.

Hello!
I have a Fujitsu laptop which I have been using for about 5 years already.
Recently there was a problem around the power port/switch and I sent it for repair, and I asked the technician to help me clean the cooling fan too.

However after using for about a month or two, another problem came and my laptop suddenly switches off after using for a few minutes or after two hours…
And when it does, the battery charging light indicator flashes.
I have been using my laptop without the battery and it fully operates just by the adapter.
And I know it’s not my adapter problem as I have tried using another adapter and this problem still occurs.
I have tried moving the adapter tip inside the DC jack connector and the battery indicator flashes too.
Do you know if this problem is caused by a failed DC jack connector or due to Overheating or whether the cooling fan is not operating properly?

Hope to hear from you soon!

I have a samsung laptop which i bought in 2013 it has i5 processor and 750 gb hard disk 4gb RAM. one day while i was working with it every thing was stuck up. First i was confused so i, waited for a while but the problem was unsolved so i switched my laptop off for a while and took the battery out. when i restarted it. My system doesn’t work. it said automatic repair and took 10 min and then blue screen error occured. i tried installing other windows OS. But it was of no use, my OS doesn’t get installed. I don’t know whether it is hard disk problem. because i tried installing linux using a pendrive and linux works fine when i keep the pendrive to my laptop but if i take out OS does not work again. So can u help me solve this. Thank you……………..

The other day, I’d hit my Compac (laptop) and had shown a blue screen before giving the options of ‘How to Start Windows’ or something close to that, choosing either the “Diagnose Problems” or the “Start Windows Regularly” all lead to the “Starting Windows screen” to the screen after that (where it shows only the cursor and a blackish screen) it stays there for several minutes, and won’t change after a while. I’ve also tried turning it off and on regularly but nothing else helps. Any ideas?

My laptop is making repetitive beep sound at startup, and after it is turned on, the mouse pad isn’t working properly and moreover if I click on any file/folder dialogue boxes of “send this file to recycle bin” opens up one after the other. Neither clicking on yes or no is of any help.
The problem subsided on its own for a while but came back again after sometime.
While entering the password to unlock the computer, I have to use the Shift button, then I saw that the letters of my password got deleted, i.e., I concluded that Delete button has remained pressed (has gone faulty) because one Shift+Delete can do the work of Backspace button.
Am I correct in my conclusion, if yes, then what is the way out of the problem ??
Can there be a case of malware/virus ??

Okay..so today/tonight when I restarted my laptop Dell Inspiron 15(I bought back in 2009) and this has happened a few times before…I logged my room mate into their window account(long story) and it said display stopped working properly it said this: Product
Windows

Problem
Video hardware error

Date
10/8/2015 5:11 PM

Status
Not Reported

Description
A problem with your video hardware caused Windows to stop working correctly.

I had to hard shut down my laptop because my monitor(my laptop is hooked to a monitor because my laptop screen is broken) went black..shut off. When I turned it back on..and signed into the admin account(my account) it did the same thing..so I did a “cold shut down” again and it worked. What do I do about this…I don’t want it to happen again. I do not like sharing a account due to certain issues that I don’t want to go into(trust issues and sites the room mate goes into….not to mention they’ve screwed me over..and changed my password on me before)

Point being and sorry about the paragraph..can you help me on this.. I’d like to keep it so that I don’t have to share a account and also so I don’t fry the laptop for good, etc.

Hi!
My laptop condition is quite similar to 8! It was working fine whole day suddenly distorted images start appearing, though it never fell off, no heavy object was placed over it.
Don’t have idea what suddenly happened, I unplugged it, removed battery then again started but no use.
Could it be due to over heat? Suggest way please.

my hp 200 laptop turned on and half of the screen wasn’t normal. I turned it off removed the battery. When I refixed the battery the red light which indicates turning on shows then after a while it goes off without any thing showing on my screen. I tried several times but thesame thing. Light comes on on the keyboard but screen remains blank and after a while the red light goes off.

please help me to answer my assignments.
1. NO VIDEO OUTPUT
-When you open your PC, nothing shows up in your monitor and the LED indicator of your monitor is flashing in yellow color.2. NO VIDEO OUTPUT
-Same as number one but now the LED indicator of your monitor is in steady orange color.
3. DOESN’T BOOT
– When you open your PC it will show the processor’s brand and/or the motherboard’s brand but doesn’t continue. Usually this error will result to system restart over and over again.
4. NEVER ENDING LOADING OF OPERATING SYSTEM
– The computer opens up then boots but when the operating system loads it, doesn’t continue and it will take a longtime if you’re going to wait for it to load.

5. KEYBOARD AND MOUSE SYSTEM RESTART
– This will happen only in standby mode, when you move your mouse or type something, your system will automatically restart and the worst part is it will delete a file at random.

6. SOUND ON/OFF ERROR
– Upon loading the operating system, you will hear a loading sound and then the sound stops, when you try running an audio file, no sound will be heard.

7. APPLICATION CAUSES SYSTEM TO RESTART
– Just like the mouse problem, when you open a program that will take the whole screen like for example a game and/or a program applications, when you close it, it will cause your system to restart.

please i need your help .thank you

My problem is same as NO. 5. Happening for last 4/5 days when i play games. it goes about 90-95 degree Celsius in processor, gpu, motherboard, and shuts down without any notice. Sending it to the service center. Is that any big problem? anything that is major? I am very afraid about that. I love my laptop very much.

Hello,
Are you still answering questions on this blog? Also, maybe you can archive some of those older questions under categories.

Any way, hopefully you are answering people via their emails b/c I am desperate for help! So much so that I’d be HAPPY to donate once I receive an answer from ya… is it working?? Lol! Hey! I said I was desperate. 😉

So, I have a Dell Inspiron. Sorry, I forget which number but I think it’s a 2100 series. But again, I may be wrong. I don’t dare turn on the computer.

Intermittently over a few months I’d get a BIOS pop up that said: Display Driver Stopped Responding but has recovered.

After a few time of checking a driver update was finally available. Then it stopped giving me the pop up.

Then after a few months it happened again and again. Then a few days ago I was working on a client’s website and I looked away for a moment, looked back and the screen was a solid mid green color!

Had to do a hard reset. It took forever to reboot. Then I ran a diagnostic test which said that the System Memory Failed. And the Advanced Pattern Test WME22-OID Failed. (I am uncertain about the last three characters. Ie, rather it’s an alpha O or a numerical 1. And the same with the 2nd of the last 3 characters).

Any idea about what is causing this problem? Maybe the memory became unseated when it fell off my ottoman? Or maybe a motherboard failure? Or memory card failure? Or some other hardware failure?

Your time and efforts to assist me would be greatly appreciated! Ty and Happy Holidays! I hope you’re having a spectacular season

need a help,
I have new ASUS F555U laptop. I tried installing intel(R) HD graphics 520 several times. But it didn’t work. After that i had safe mode reboot to check the the drivers using device manager. At that time I saw some yellow balloons.Now they seems to be fixed. but I think since then it started to make a intermittent faint beep sound with in the laptop, not by speakers. when i move the mouse pointer it sounds and also at some other random times. when i plugged, the sounds increased little bit more. i am using windows 10. And the search options of the windows are not also working.(cortana in windows 10). I am not sure whether it is a windows problem or hardware problem?
